by Shiu-Tang Li

1. Brief introduction, and some remarks to this interactive EDA

In this report, A few interactive maps / pie charts are created to help the readers gain intuition on FARS dataset, including the visualizations of a few major factors (drunken driving, non-motor vehicle occupant deaths, weather, number of persons died in an accident).

The data set

FARS 2013-2015 dataset contains 50-52 features (differed by years), and contains 92,424 observations (30202, 30056, 32166 obs for year 2013, 2014, 2015).

The FARS data set can be downloaded from ftp://ftp.nhtsa.dot.gov/fars/, and the full description of the FARS dataset can be downloaded from https://crashstats.nhtsa.dot.gov/Api/Public/Publication/812315 .

In this report, all data with wrong longitude or latitude (say latitude = 999.99) are removed (722 obs).

Additional Information as you hover the cursor over the map..

Format: Month/Day/Year(Weekday), 24 hour time format, number of persons killed, first harmful event (major reason that causes death)

Create a customized EDA report!

You could create an analysis report for any state you like, by specifying the state abbreviations (All 50 states + Washington D.C., not including Virgin Islands and Puerto Rico because there’re no data) in the .rmd file. The default is “UT” (Utah).
